• A. 2 hours
• B. 8 hours
• C. 12 hours
• D. 4 hours

Answer: (D)

Maintaining animals in a comfortable environmental range is essential for welfare, so the standards cap how long temperatures can stay outside that range while animals are present. If ambient temperature goes above 85°F or below 45°F for more than four hours, corrective action is required to protect the animals. Four hours is set as the maximum exposure duration to limit heat stress and cold stress, which can lead to dehydration, metabolic strain, and increased illness or reduced productivity. Shorter periods outside the range may be tolerable if watched and mitigated, but the question is asking for the maximum allowed duration. Exposures lasting longer than four hours would exceed the standard, even though shorter options exist within the limit.
